Pinion P1.18 gearbox

4 / 16

The Pinion gearbox—an enclosed, multiple-speed, transmission—has 18 speeds spanning an extremely wide range—636 percent. The internals are exposed in this picture, but would be enclosed in a production unit, sealed and protected from the elements. Like other internal gear systems, Pinion eliminates vulnerable external elements like derailleurs. Additionally, the company claims the design lowers a bike's center of gravity, and moves it to the center, improving handling and balance. The Pinion requires a purpose-built frame and the company currently has 36 partners building bikes of all types around the system.
